Abstract

The aims of this study were; to evaluate the skeletal and dental characteristics of both the mandible and maxilla in patients with Class II division 1 malocclusion using different cephalometric measurements, to determine sex differences and to define the basic characteristics of Class II div 1 malocclusion by comparing the data with Turkish norms. The sample of the study consisted of 100 subjects (48 males, 52 females) aged between 8-14 years (mean age 12 years 8 months ± 1 year 6 months). Four different analyses were employed to evaluate the skeletal and lateral properties of both the maxilla and mandible. Subsequently the results of the analyses were compared with Turkish norms described by Basciftci et al. Student t-test was used to compare the data with Turkish norms and to determine the sex differences. The results of the study suggest that the subjects with Class II malocclusion tend to have normally positioned maxilla and retruded mandible in sagittal direction and those lower and upper incisors are inclined and positioned within acceptable range, showing normal vertical dimensions relations. The only difference between sexes was the value of U1-NA (°). Females were found to have protruded upper incisors. Statistically significant differences were found between the finding and Turkish norms except for the A Nasion perpendicular distance and L1-NB angle. As a conclusion, the results of this investigation suggest that the patients included in the study sample tend to have normally positioned maxilla and retruded mandible.

Özet

Bu araştırmanın amacı Sınıf II bölüm 1 maloklüzyona sahip hastalarda maksilla ve mandibulanın iskeletsel ve dental pozisyonunu farklı sefalometrik göstergeler aracılığıyla değerlendirmek, cinsiyet farklılıklarını belirlemek ve elde edilen Sınıf II bireylere ait ölçüm değerlerini mevcut Türk normlarıyla karşılaştırarak maloklüzyonu oluşturan temel öğeleri ortaya koymaktır. Sınıf II maloklüzyona sahip 8-14 yaş aralığındaki 48 erkek, 52 kız; toplam 100 birey (yaş ortalaması 12 yaş 5 ay ± 1 yaş 6 ay) araştırma kapsamına dahil edildi. Araştırmada maksiller ve mandibuler iskeletsel ve dental pozisyonların tespitinde 4 farklı analize ait ölçümler kullanıldı. Başçiftçi ve ark.'ları tarafından oluşturulmuş Türk normları referans standart olarak alındı. Cinsiyet farklılıkların tespitinde ve bireylerin iskeletsel ve dental ölçümlerinin Türk normları ile karşılaştırılmasında student t-testi uygulandı. Genel olarak incelendiğinde Sınıf II maloklüzyona sahip bireylerin sagital yönde normal konumda maksiller ve retrüziv mandibuler kaideye sahip oldukları, alt ve üst keserlerin normal eğim ve konumda oldukları ve normal vertikal boyut ilişkisi gösterdikleri belirlenmiştir. Cinsiyetler arasında fark sadece U1-NA (o) ölçümünde bulundu. Kızların daha önde üst keserlere sahip olduğu ve farkın istatistiksel olarak anlamlı olduğu görüldü. Türk normlarıyla yapılan karşılaştırmalar sonucunda A noktasının Nasion vertikale olan mesafesi ve L1-NB açısı hariç tüm verilerde istatistiksel olarak anlamlı farklılık tespit edilmiştir (p
